Answer:
6x³ - 8x + 9
Step-by-step explanation:
Step 1: Write out expression
2x + 7 + 6x³ - 1 + 3 - 6x - 4x
Step 2: Combine like terms (x)
6x³ - 8x + 7 - 1 + 3
Step 3: Combine like terms (constants)
6x³ - 8x + 9
Answer:
Step-by-step explanation:
You can use the sin function,
cos x= adj/hyp
cos x= 14.3/19=0.752
x=arcos 0.752= 41.18 degrees
400 x .25 = x
Change the 25% into a decimal
400 x .25 = 100
